Teradata has bought the assets of Revelytix and Hadapt in a bid to grow out its capabilities for the Hadoop big-data processing framework.

Revelytix developed Loom, a metadata management system compatible with a number of Hadoop distributions, including those from Cloudera, Hortonworks, MapR, Pivotal, IBM and Apache, according to its website. Loom is geared at helping data scientists prepare information in Hadoop for analysis more quickly.

Meanwhile, Hadapt is known for its software that integrates the SQL programming language with Hadoop. SQL is a common skill set among database administrators, who may not be familiar with Hadoop.

Last week, Teradata rival Oracle announced Big Data SQL, software that makes it possible to run a single SQL query against Oracle's relational database as well as Hadoop and various NoSQL information stores.

There are a number of other SQL on Hadoop implementations in the market as well, such as Cloudera's Impala and Pivotal's HAWQ.

Teradata will add Hadapt and Revelytix's employees and intellectual property to its Teradata Labs research and development arm, according to a statement released Tuesday. Terms of the deals were not disclosed.
